Men's Suit Size & Measurement Guide

Compare jacket and trouser sizes below, then follow our 14-step measuring guide. Our default sizing is US. Choose inches or centimeters and compare Short, Regular, and Long jacket lengths.

Jacket and trouser size numbers use different scales. Before choosing a size, confirm whether the chart for your selected suit lists body measurements or finished garment measurements. If you are between sizes, ask for sizing advice before ordering.

How to Measure for a Men's Suit

Use a flexible cloth tape, wear a lightweight shirt and trousers, and stand naturally. Ask a helper to take shoulder and length measurements. Keep circumference measurements level and comfortably snug. Record every measurement in the same unit and measure twice.

1. How to Measure Upper Body Length

Lift your shirt collar. Place the start of a flexible cloth tape where the shoulder seam meets the base of your neck. Measure vertically down the front, over your stomach, to the point where you want the jacket to end. Record the exact endpoint; finger position is only a style reference.

2. How to Measure Chest

Wrap the tape around the fullest part of your chest, under your armpits and across your shoulder blades. Keep the tape level and comfortably snug without compressing your chest. Stand relaxed and breathe normally.

3. How to Measure Hips

Stand with your feet together. Wrap the tape around the fullest part of your hips and seat, keeping it level all the way around.

4. How to Measure Waist

Wear your trousers without a belt. Measure around your body at the height where you want the trouser waistband to sit. Keep the tape comfortably snug. This position may differ from your natural waist.

5. How to Measure Shoulder Width

Ask someone to help. Start where one shoulder seam meets the sleeve and measure across your upper back to the same point on the opposite shoulder. Follow the natural shoulder curve near the base of the collar.

6. How to Measure Arms / Sleeve Length

Start where the shoulder seam meets the sleeve. Measure down the outside of your arm to your desired sleeve endpoint. If measuring to the web between the thumb and hand, clearly record that endpoint rather than assuming it is the finished jacket cuff position.

7. How to Measure Your Neck

Wrap the tape around the lower part of your neck where a shirt collar sits. Stand relaxed and adjust the tape to a comfortable fit without pulling it tight.

8. How to Measure Armhole

Ask a helper to loop the tape over the top of your shoulder and under your armpit, around the shoulder joint. Lift your arm only to position the tape, then lower it naturally. Do not confuse this measurement with biceps circumference.

9. How to Measure Biceps

Let your arm hang relaxed at your side. Measure around the fullest part of your upper arm without flexing your biceps or compressing the skin.

10. How to Measure Thighs

Measure around the fullest part of your upper thigh, just below the crotch. Keep the tape level, allowing room for one finger between your thigh and the tape.

11. How to Measure Pants Length / Outseam

Wear the shoes you plan to pair with your trousers. Place the tape at the top of the waistband on the side of your trousers. Measure down the outside of your leg to your desired hem. The top of the shoe heel can serve as a reference, depending on your preferred trouser length.

12. How to Measure Crotch / Total Rise

Close the trouser zipper or buttons. Measure from the center back waistband down between your legs and up to the center front waistband, where the belt buckle would sit. Keep the tape comfortable. This full measurement is not the same as the Front Rise listed in the trouser chart.

13. How to Measure Waistcoat Length

Lift your shirt collar. Start where the shoulder seam meets the base of your neck and measure vertically down the front, over your stomach, to your desired waistcoat hem.

14. How to Measure Coat Length

Lift your shirt collar. Measure from where the shoulder seam meets the base of your neck down the front to your desired coat hem. Possible reference points include just above the knee for a long coat, mid-thigh for a three-quarter style, or around the thumb knuckles for a short coat. These are style preferences, not fixed size standards.

Before You Order

US sizing is the default. Jacket and trouser size numbers use different scales. Confirm whether the chart for your selected suit lists body measurements or finished garment measurements before comparing your measurements or adding ease. Short, Regular, and Long describe length options, not universal height ranges. Trouser outseam and full crotch length are not included in the trouser chart. If measurements fall across different sizes, ask for sizing advice before ordering.
